BOAT.

Specification of Letters Patent. Application filed January 7, 1911.

Serial No. 601,422.

To all whom it may concern:

Be it known that I, JAMES E. CHURCH, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Boats, of which the following is a specification, reference being had tothe accompanying drawings, forming part thereof.

This invention has reference to boats having hulls of. the catamaran variety and adapted to be manually operated.

One obje t of the invention is to so construct a boat of this nat-ure that it may be utilized as a natatory exercising machine for one orfmore persons.

Another object of the invention is to so construct, a boat or catamaran having a pair of hulls or floats that said hulls or floats may be readily adjusted parallel to each other and automatically locked in the adjusted positions.

Another object of the invention is vide a novel driving general character.

The invention consists in such peculiar features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, represents a plan view of the to progear for boats of thisl improved boat in its preferred form. Fig..

2, represents a sectional view thereof taken on line 2-2 Fig. 1, parts of the same being shown in full line. Fig. 3, represents a partial sectional view taken on line 3-3 F' 1, showing a detail of one of the locking bolts and its lever, for locking the outriggers in position. Fig. 4, represents a plan view of the boat showing the same modiiied to adapt it to the use of several persons. Fig. 5, rep* resents a sectional view takeny on line 5-5 Fig. 4. l

Similar numbers of reference designate corresponding parts throughout.

As shown herein in its preferred form 10,

10 indicate hulls or floats of any suitable.

construction and shape to sustain their load,

with the operator, partially immersed, when in use. Pivotally connected with these hulls or floats 10, 10 are t-he arms 11, 11 and 12, 12 of which the arms 12, 12 are pivotal-ly connected with the member 13 while the arms 11, l1 are mounted to swing on the pivots 14, 14'of the central member 15 whereby said hulls or floats may be adjustedrforward or backof the position shown in full lines in Fig. 1, one of such adjustments being 'stops for the having the lever 22.

. or pulley' 28 having tends rearwardly from the 'said members 13 and 15 or tiller line tubes 33,

shown in dotted lines in said Fig. f11. In order to effect such adjustment, and to lock the Outrigger arms 11, 11 in the adjusted position, I provide the inner ends of said arms 11, 11 with tubular bearings 16, 16 having formed in their walls the cam slOtS 17, Fig. 3, of which the ends 18, 19 form pin 20 of the locking bolt 21 The central member 15 has the two series of sockets 23, 23 with any of which the bolts 21, 21 of t-he respective arms 11, 11 may be brought into registry by the swinging of said arms on their pivots 14, 14. In the operation of these locking mechanisms one of the levers 22, 2-2 which are positioned 'at different heights so that they may clear one another as shown in Fig. 3, is swung to effect the partial rota tion of its bolt 21 in which movement pin 2() rides up one inclined edge of the cam slot 17 until the end or stop 18 or 19 of said slotlimits the further movement of said pin while the continued pressure on the lever 22 effects the swinging of the particular outrigger arm 11 on its pivot 14 and the corresponding movement` forward or back, of the related hull or flo-at 10. When the desired position reached the lever 22 is swung, with relation to the bearing 1G, to a point where the cam 17 permits or effects the engagement of bolt 21 with the socket 23 thus in registry with said-bolt.

vFrom the central member 15 extends the bracket plate 24 having the tubular bearing 25 fc the shaft 26 having at its upper end the helm 27 and at its lower end the wheel to receive portions of the steering lines 29, 29 which are led through perforations 28', 28 in the` rim of the wheel 28 and are wound on the take up shaft 30 journaled in said wheel 28 and having the handle 31 by means of which said shaft 30 may be rotated to take up or shorten said lines 29, 29 at times, to be hereafter referred to.

Mounted on the members 13 and;15 is the platform or plane 32 which, preferably, ex-

member 13. In extensions therefrom are mounted the 33 and the shaft tube 34 in which, respectively, are slidably mounted the tubes 35, 35 having the branching; ends 36, 36, and the shaft 37 which latter carries the rudder frame 38 W'ng the. upright member 39 Patented Oct. 17, 1911.'

of adjustment has been' grooves in its periphery I nwhich is titties the. hollow Water tight float 40 'forming a rudder and having the .tiller yoke 41 to which the tiller lines 29, 29

extending through the tubes 33, 33 and 35, 35 are secured. On the shaftA 37 near the member 39 is' rotatably mounted the sleeve .42 having the propeller 43 and the bevel pins l44,.and on said shaft 37, adjacent the end of said sleeve'42 is mounted the member 45 in a transverse bearing of Which is journaled the crank shaft 46 having the pedal arms 47, 47 and the large bevel gear 48 Which drives the pinion 44. Thet'ubes 35, 35 and the shaft 37 are slidable for the purpose pedals with his feet to drive the propeller 43 While being Within reach of the helm 27 are .adjusted thetiller lines 29 are taken up to .effect the swinging of the rudder 40. At the 4time said tubes-35, 35 and the shaft 37 or letout by' rot-ating thershaft 30. f In the modified construction shown in 25 Figs 4 and 5 the hulls or floats 10, 10 are extended lengthwise sufficiently to sustain several. operators and additional pairs ot Y Outrigger arms 12, 12 are provided to sus- 'tain the central members 13, 13 and their platforms 32', 32 having their forward ends turned upward to form shields 32, 32. In

this construction the tiller lines 29 are carried through. the tubes 35, 35 which are yiXed in the central members 13, 13 and said .35

lines are secured to the yoke 41 as in the preferred construction. On said tubes are mounted bearing members 50, and 51 in which are journaled the pedal shafts 52, 52

having the gears 53', 53 which mesh with plnions 54, 54 of the propeller' shaft 55 'journaled in bearings in the members 13,

13 and 50, 51 and having the propeller 56. By this modified construction the improved boat is adapted for use by a crew each meml ber of which lies upon one ot the alatforms 32 or 32 and drives one of the pec al shafts 52 by operating its pedals With his feet whereby the shaft 55 and its propeller 56 is rotated. The craftis steered by that member of the crew on the platform 32 by means of the helm 27.

Having thus described my invention I claim as new and desire to secure by Letters Patent- 1'. A boat comprising a pair of hulls, outrigger arms pivotally connected with said hulls, a. central member to which the inner ends of said arms are pivoted, said central member having series of sockets, bolts carried by said arms'and engageable with said sockets, and levers, mounted on said arms, for operating said bolts and for eitecting the swinging of said arms on their pivots.

2. A boat comprising a. pair of hulls, outrigger arms pivotally connected with said hulls, central members to which the inner ends of said arms are pivotally connected, tubular supports carried by said members, tubes slidable in said tubular supports, a propeller sustaining member slidable in one of said supports, a rudder trame mounted on said propeller sustaining member, a floatable rudder pivotally mounted in said frame tiller lines connected With said rudder an( extending through tivo ot said tubes, a propeller rotatably mounted on said propeller sustaining member, and pedal driven gear for operating said propeller, substantially as described.

3. A boat comprising a, pair of hulls, outrigger arms pivotally connected with said hulls, central members to which the inner ends of said arms are pivotally connected tubular supports mounted in said centrall members, a rudder frame sustaining member slidable in one of said supports, a widder pivotally mounted in said frame, tiller lines extending from` said rudder, and a take up device for said tiller lines rotatably mounted on one of said central members and having a tiller substantially described. j
